An attacker able to inject content into the renderer, such as by forging the /pc/upgrade/get API response using a publicly known AES key over an unvalidated TLS connection, can invoke os.navigateExternal with a file:// URL through an img onerror payload to execute arbitrary local binaries under the logged-in user's account.","publishedAt":"2026-10-12T19:33:32.062Z","updatedAt":"2026-10-26T20:35:47.341Z","severity":{"score":9.2,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["NetEase NetEase Cloud Music for Windows"],"affected":[{"vendor":"NetEase","product":"NetEase Cloud Music for Windows","defaultStatus":"unaffected","versions":[{"version":"3.1.38","status":"affected","versionType":"custom"},{"version":"3.1.39.205426","status":"affected","versionType":"custom"}]}],"references":["https://gist.github.com/LeoWSY-hashblue/10e5383fc2d4d75faf74a9507c6bba9f","https://hr.163.com/product.html/music","https://www.vulncheck.com/advisories/netease-cloud-music-rce-via-os-navigateexternal-ipc"],"weaknesses":["CWE-749"],"ingestedAt":"2026-10-29T20:10:33.477Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/109xxx/CVE-2026-109422.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-109422","state":"PUBLISHED","datePublished":"2026-10-12T19:33:32.062Z","dateUpdated":"2026-10-26T20:35:47.341Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-10-12T15:52:36.681Z"},"containers":{"cna":{"title":"NetEase Cloud Music RCE via os.navigateExternal IPC","descriptions":[{"lang":"en","value":"NetEase Cloud Music client for Windows (cloudmusic.exe) versions 3.1.38 and 3.1.39.205426 contains a remote code execution vulnerability in the renderer-process IPC bridge os.navigateExternal, which passes caller-supplied URLs to ShellExecuteW without validating the URL scheme.
